Local Positioning System for Position-Time-Condition Correlation, Data-logging and Analysis

Description:

This CDC-developed technology describes an automated system for monitoring worker hazard exposures by recording data about where and when hazards occur in a workplace or other environment. This allows the hazards to be avoided and harmful exposures and risks reduced. This field-tested technology consists of an integrated, hand-held electronics instrument and software system that will precisely correlate multiple exposure levels with position coordinates of the user and features real-time data acquisition.

Workers in many outdoor occupations move about frequently during a typical day of work. Certain workers, such as agricultural and construction workers, are particularly mobile. This exposure monitoring system combines geographical location with real-time sensors and outputs the information to a user-friendly interface. By linking worker location throughout the workday to exposure levels from real-time monitors, Local Positioning System (LPS) units (with integrated software processing of data) identify and document where to direct hazard exposure analysis and control efforts. Post-processing of LPS data enables researchers, regulatory inspectors, and industry safety and health personnel to map exposure intensity and location, reveal hot spots to identify sources, and provide exposure intensity distributions to increase workplace safety.
